<h2>Plot-Files</h2>

<p>The programs <a href="SP_SED.htm">SED</a> and <a href="SP_PREDOM.htm">PREDOM</a>
read input <b>data-files</b> and create output <b>plot-files</b>. Plot-files have
<nobr>&#147;<b>plt</b>&#148;</nobr> as the file name extension, while input data-files have
<nobr>&#147;<b>dat</b>&#148; as extension.</nobr></p>

<h3>Display and Print Diagrams</h3>

<p>You can display and print plot files with the <a href="S_0_Main.htm">SPANA</a> program.</p>

<p>There are also two programs to convert plot-files to other formats:
<ul type="square">
<li><nobr>PlotPDF:</nobr> converts a plot-file to
    <a href="SP_PDF.htm">PDF</a>.</li>
<li><nobr>PlotPS:</nobr> converts a plot-file to
    <a href="SP_PostScript.htm">PostScript</a>.</li>
</ul>

<p>These programs may be <a href="SP_Batch_Mode.htm">run in <nobr>batch-mode</a>.</nobr>
This makes it possible to automatically manage large lists of diagrams.</p>

<p>These programs have an option to read the colours stored
in <nobr><a href="S_0_Main.htm">SPANA</a>&rsquo;s</nobr> &#147;ini&#148;-file
<nobr>(<tt><a href="1_Install_Uninstall.htm#INI">Spana.ini</a></tt>).</nobr> With this option the PDF and PostScript files
will have the same colours as those displayed in the diagram windows of the SPANA program.</p>
